Web Hosting Talk : Web Hosting Main Forums : Hosting Security and Technology : Copy or Rename files *.JPG as *.jpg

[hbhb]

I have hundreds of files with a .JPG extension on a directory.

I wanted to mass-copy or rename it as .jpg (small case), without overwriting existing file (if file exist)

For example:
abc.JPG -> abc.jpg (Fail: file exist)
abc.jpg
xyz.JPG -> xyz.jpg (Success)

Anyone can help? I try to search for the right command or script to do that but to no avail..

I hope you are using a *NIX based machine.


Here you go.

for i in $(ls -1 *.JPG)
do
pre=$(echo $i | cut -d "." -f1)
cp -v $i ${pre}.jpg
done



Please run it on bash.

This is for copying , if you want to rename use mv instead of cp

[hbhb]

will it prompt question to overwrite file (y/n?) because i have over 500 files

[helpyoulinux]

In that case, you have to use

cp -f

it will do the trick.

Supposely I do not want it to overwrite file. Default answer should be a 'NO'

-f sounds like 'force' to 'YES' ?

If you do not want to overwrite then use the command

yes n | cp source destination
